I was able to figure out which article he was referring to. It is the following:

Lei, P. W., & Koehly, L. M. (2003). Linear discriminant analysis versus logistic regression: A comparison of classification errors in the two-group case. The Journal of Experimental Education, 71(1), 25-49.

I was able to get it online through another database. Thanks. Dennis Fisher
